In Germany August 16, 1932 3 Claims. (01. 101-93) v This invention relates to type line composing and printing machines using circulating patrices which are taken out of magazines, set in lines, inked, printed and restored into the magazines again- In such line setting and printing machines the set line is printed on one side of a transparent sheet stretched over a printing cylinder. This method is, however, unsatisfactory, as a proper covering of the printed types, is not obtainable due to the particular nature of the surface of the printing sheet, and furthermore such printed pattern sheets are only applicable as patterns for intaglio printing plates, whereas, for the production of plates for offset printing only pattern sheets that are printed on the backside (positives) are used.

According tothe present invention, the transparent printing on both sides is rendered possible with aline setting and printing press by means of a printing mechanism wherein the inscription image of the inked lines is taken up by a resilient base, forexample, rubber and then printed therefrom together with the type lines after the interposition of the transparent sheet thereon.

In machines of the previously-mentioned kind, this permits of transparent printing with good covering of, the printed type, as the resilient base permits of easy printing (impression) but which, however, is sufficient for covering the 'type. These transparent sheets, may'thereby be used as reproduction copies for offset as wellas for intaglio printing.

,The shifting of the printed sheet and the base is effected by means usual inthe printing art by means of a line shift device.

The sheet is interposed in the printing position preferably on a carriage running on rollers.

In the accompanying drawings a constructional form of the invention is illustrated by way of example only, in which Fig. 1 shows afront elevation of the printing ,device of-the machine with the parts in inoperative position,

Fig. 2 shows a side elevation of the same with the parts in inoperative position and the driving mechanism omitted,

Fig. 3 is a view of the feed device for the paper slide,

Fig. 4 is a view of the feed means for'the printing cylinder inclusive of the printing form, and

Fig. 5 shows a side elevation of the machine with the parts in printing position inclusive of the various driving members.

In the magazines I, which are vertically directed, the patrices 2 are stored.

The key-board 3 is connectedin a usual man.- ner with the magazines I. The collecting device 4 connects the magazines I with the collecting channel 5 which serves as a guide for the patrices I on their way to the printing device. A spacing device or justifier 6 of conventional construction secures the collected patrices in their relative positions. A cylinder 9, which carries the resilient printing form I0, is mounted for rotation in the printing carriage 2| and adapted to be displaced in unison with said carriage in the vertical direction by means of the guide 22 for the print- Y ing carriage. Y

A tension bar 24 attached to the printing carriage M by m ans of a pin 23 is connected at its other end with a control lever 29, which is provided with a guide roller 26, by means of a pivot 111 x125, said lever in turn being pivoted to the shield 28 of the machine frame at 21. The roller 2% runs on a cam disc 3I carried on the main drive shaft 36, thus imparting to theprinting carriage M a downward motion against theaction of a compression spring32. 1

Behind the printing carriage 2| an inking device I of a usual construction isarranged which supplies two inking rollers 8 withcolor. A cam disc 33 actuates a two-armed lever 35 mounted on a carrier as and provided with a guide roller 36 and a pivot pin 3? to which the pusher arm 38 v is connected the other end of which carries the inking rollers 8 in rotatable manner. Two upwardly bowed rails 20- act as a guide forthe-inking rollers 8 on their travel across the patrices '2. A tensioning device I9, as usually combined with printing cylinders, permits of spreading the printing form It on the cylinder 9 in a stretched condition. On the pivot 39 of the'cylinder 9 a feed lever Ill carrying a pawl 40 is rockably arranged, the other end of this lever slidingin a guide loop ii, whereas the pawl 40 engages in a ratchet wheel 32.

is actuated by a control arm 48 through the in- "terrnediary of a link 61.

A guide roller 49 arranged on the outer end of this link cooperates with a cam disc 50 on the main drive shaft '30. A tension spring 5i attached to the lever I6 urges the latter on the cam disc 50. In the paper slide it a paper carrier frame I2 is displaceably arranged. I 3 designates a transparent sheet which in a usual manner is secured by clamping rollers I I to the frame 2 a toothed portion of which cooperates with a gear wheel 52 which is connected to a ratchet wheel I8 by a shaft 53 '(Fig. 3). A-pawl 55 carried by a two armed. spring pressed lever 56 cooperates with the ratchet wheel I8 and is controlled by a stop 55 adjustably arranged in a support 5'! on the bracket 43.

The operation of the above-described arrangement is as follows:

Thepatrices 2 contained in the magazine I are released by depressing the keys 3 and thus caused to pass through the collecting device 4 into the collecting channel 5- through which they are conveyed as a set line under th e, cylinder 9 by the spacing or justifier device '6. Thereupon, the cam disc 33 operates the two-armed lever 35, so that by means of-the pusher arm 38 the two inking rollers 8 are moved away from the inking device along the guide rails 20 andacross the patrices 2 united into a set line for'inking in the same.

i The inking rollers 8 remain at rest inthe'posi tion shown in chain dotted lines in Fig. 5, while the cam disc 3| moves the controllever 29 and thus the tension bar 24 so as to displace the printing carriage 2i downwardly'in its guide 22 until the printingform l0 overlying the cylinder 9 contacts with the inked in set line of ,patrices.

When the cam disc 3| rides oiT the roller 26,

the spring 32 forces the printing carriage upwards some distance, whereupon the lever 35 returns together withthe pusher arm 38 and the inking rollers 8 int inoperativeposition in such manner that the-inking rollers 8, during their retracting movement, ink in the patrices 2 anew, whereby the. ink layer is greatly reinforced and the'printed copy is-completed, and the rollers subsequently are returned to the inking device. Then a the lever it moves the paper slide l5 fastened to its outerend into the position shown in Fig. 5

-by tension action of the spring 5|, as at this time the cami;disc 50 releases the control arm 48, so

. -that the spring 5| is 1"endered operative.

As soon as the paper slide assumes its end position and the transparent sheet l3 clamped to the paper frame 12 is inserted between the set f line of patrices and the cylinder 9 the latter is lowered for the, second time to press the sheet -I3 against the patrices 2 and simultaneously transferring the ink present on the printing form 10 to the sheet l3, whereafter the latter sheet is printed on both sides. After the cylinder 9 has 7 been raised again by action'of the spring 32, the

cam disc forces the paper slide I5 back into position of rest by means of the control arm 48,1ink41 and 'leve'r l6. During the movement of the paper slide l5into the printing position,

v the pawl carrier lever 56 hits the stop 55. and

- the pawl 54 rocks the ratchet wheel l8 and thereby the gear wheel 52 to the desired extent, so that the transparent sheet I3 is advanced together 'With the paper carrier: frame bythe distance between two lines. During raising the printing,

carriage 2| into' inoperative position, the feed lever [1 hits the upper end of the guide loop 4| and the, pawl 40 rotationally displaces the cylinderfor such an amount about its pivot 39, that an unused portion of the printing form I 0 is moved into printing position.

I-'do' not limit myself to the particular size, shape, number orarrangement of parts as shown and described, all ofwhich may be varied without going beyond the scope of myinvention as shown, described and claimed. 65
